Peptides are the chemical compounds which consist of amino acids coupled together by peptide linkage. Peptide derivatives are synthesized by coupling the carboxyl group of one amino acid with amino group of other. Due to the possibilities of fortuitous and unintentional reactions, various protecting groups are used to protect the carboxylic acid as well as amino groups of both the amino acids. These peptide derivatives are associated with a variety of pharmacological activities including antibacterial and antifungal activities. While doing our analysis some of the dipeptides were synthesized in a reasonable yield and purity which were fully characterised by FTIR and H1 NMR. The antimicrobial activity of these derivatives was studied and these were found to be active against two strains of fungi (Aspergillus fumigatus & Pencillium chrysogenum) and two strains of bacteria (E. coli and Salmonella typhimurium). This provides for a future insight to work on the synthesisof these dipeptide derivatives to achieve their stability.
